How much do those mentholated honey/lemon drops actually help a sore throat?

I have strep. I’m a big baby. I bought two bags of drops. One is honey and lemon with 10mg of menthol, and the other one is strawberry with less menthol, I don’t remember how much. They’re both disgusting.

I sucked down one of the honey lemon ones, and it didn’t seem to soothe it for very long. Should I have bothered, or did I just waste $5?
